Hi Tarek,
I A-10 checked out different sites for 70 mm jets. Mnay have been disciontinued. I will give you a list to consult so you can choose which ones interest you and then we can discuss what would be the best choices. A twin 64 mm such as the A-10 Thunderbolt can be an option. There are also a number of non-scale models, such as the Rebel and the Habu. As I mentioned, the 64 mm F-15 may work, but it may get a bit on the heavy side, there is a 70 mm version below at Hobbyking. Very cheap!
Look at the following web sites and narrow it down.
Super cheap 70 mm F-15 below:
